The assistant services the device
"Why is the battery draining?" Caroline sees which service ate the charge and the memory, stops what is not needed, and reports what she did.
Compare
The only system built for two.
Every mainstream operating system was made for a person. Beroun is made for a person and an assistant.
Side by side
How Beroun compares.
| Android / iOS | Desktop OS with an AI agent | Cloud chat | Beroun | |
|---|---|---|---|---|
| Who the system is built for | a person | a person | a person | a person and an assistant |
| How AI controls the system | through permissions, in a sandbox | "clicks buttons" from screenshots | it does not | directly, through system interfaces |
| Installs and runs apps | no | through the UI, fragile | no | yes |
| Works in the background and in sleep | limited by platform rules | while the computer is on | no | yes, with priorities and budgets |
| What is at stake if the AI errs | a whole life on the phone | the whole computer | nothing | only its own environment |
| App returns to the same place | depends on the app | depends on the app | no | yes, a system contract |
| One format for apps and the system | no | no | no | yes, one manifest |
| App agents for the assistant | no | no | fixed plug-ins | yes, declared in the manifest, A2A |
| System buttons for the assistant | no | no | no | yes, always gets through |
Beroun at work
What a system with a manager feels like.
Awake while the device sleeps
The device is asleep in a pocket. The messaging service keeps working; an important message arrives, and the assistant wakes the screen only when it matters.
A call over everything
A video is playing when a call comes in. The service allowed to take the screen does so, and after the call the video resumes from the same second.
Close it, come back to it
Reading a file in the notepad, the owner presses Exit. Opening the app again lands on the same line.
Plenty open, nothing falls over
Memory runs short. Low-priority services step aside, idle pages move to compressed swap and flash, and the assistant stays.
One button
An elderly owner presses the assistant button and Caroline appears with a face and a voice. The system button always reaches her, whatever is open.
A job for a specialist
"Plan my week from the calendar." The calendar's agent asks "move Thursday's lunch?", Caroline asks the owner, and reports the plan. The whole chain is in the log.
A developer's first day
A web page and a manifest go onto the device and immediately get a window, saved state, a service and voice control.
What sets Beroun apart
Six things no other system does together.
A manager, not a guest
The assistant runs the system instead of asking it for favours.
Direct control
System interfaces, not screenshots and simulated clicks.
A device boundary
Full power inside the system, nothing outside it.
One manifest
Pages, services, state, file types, tools and agents in one format.
Services with budgets
Priorities, memory budgets, work in sleep, permission to take the screen.
Open to agents
App agents with a task life cycle and a bridge to A2A.
Beroun
Stop fitting AI into systems made for people.
Start from a system made for both.
